A 5x8.5 mm implant achieved primary stability in the final 1-2 mm.  The implant was then placed ~ .5 mm deeper (~ 40 Ncm) (Fig.1).  The implant, apparently having been osteointegrated 5.5 months postop (Fig.3), was placed deep, probably related to pressing the distal end of the guide too heavily.  It is difficult to restore with use of a 5.2x5.5(5) mm abutment.  There is apical bone loss (arrowheads), most likely due to the dense bone and heat during osteotomy.  Immediately post cementation PA confirms the implant distal placement (Fig.6).  The trajectory is not right, since no matter how the sensors are placed, the implant threads cannot be shown clearly (Fig.10), in consistence with the distolingual access hole (Fig.11).
